Leads me to believe that if The Undertaker is not headlining then they're probably planning on for one more match.

I'm not sure if it's Batista's time to go into the HOF just yet. I think he needs to come back for another angle to erase the bad taste of his 2014 run (which in no way was his fault). I'm kind of worried that the same fans that booed him only because of Daniel Bryan not getting the push (again, not Batista's fault) will boo him in favor of The Undertaker going in.

That and also, is he going to be available? He's stated that he wanted to come back and promote GoTG but was told "No" because "they" (whoever in the WWE) wasn't sure that it was going to be a hit. I think he should ride it out for a few more years, he's already got interest from Hollywood so there's no real need to go rushing back to the WWE.
